Ossification (lossis osteogenesis) hauv pob txha remodeling yog tus txheej txheem ntawm nteg tawm tshiab pob txha cov ntaub ntawv los ntawm cov cell hu ua osteoblasts. Nws yog synonymous nrog tsim cov nqaij pob txha.
Ib yam li ntawd, koj yuav nug, cov pob txha hu ua dab tsi?
Cov pob txha ( osseous cov ntaub so ntswg ) yog qhov nyuaj cov ntaub so ntswg , ib hom kev sib txuas ntom ntom cov ntaub so ntswg . Cov pob txha yog mineralized cov ntaub so ntswg ntawm ob hom, cortical pob txha thiab tshem tawm pob txha . Lwm hom cov ntaub so ntswg pom hauv pob txha suav nrog pob txha pob txha, endosteum, periosteum, qab haus huv, hlab ntsha thiab pob txha mos.
Tsis tas li ntawd, cov ntaub so ntswg ua haujlwm yog dab tsi? Cov classic kev ua haujlwm ntawm cov pob txha , dhau li ntawm locomotion, suav nrog kev txhawb nqa thiab kev tiv thaiv cov mos mos cov ntaub so ntswg , calcium, thiab phosphate cia thiab khaws cia pob txha pob txha.
Hais txog qhov no, ob hom kev tsim pob txha yog dab tsi?
Osteoblasts, osteocytes thiab osteoclasts yog peb lub cell hom koom tes hauv txoj kev txhim kho, kev loj hlob thiab remodeling ntawm pob txha . Osteoblasts yog pob txha - sib sau hlwb, osteocytes paub tab pob txha hlwb thiab osteoclasts zom thiab reabsorb pob txha . Muaj ob hom ntawm ossification: intramembranous thiab endochondral.
Tus qauv ntawm cov pob txha yog dab tsi?
Hauv Cov Ntsiab Lus: Qauv ntawm Cov Pob Txha Compact cov pob txha yog tsim los ntawm osteons thiab tsim cov txheej sab nraud ntawm txhua pob txha . Spongy cov pob txha yog tsim los ntawm trabeculae thiab tsim sab hauv ib feem ntawm txhua qhov pob txha . Plaub hom hlwb sib sau ua pob txha cov ntaub so ntswg : osteocytes, osteoclasts, osteoprogenitor cells, thiab osteoblasts.
